The objective of this study was to analyze, on the national level, the process of monitoring the proposed UNGASS indicators through the use of the Brazilian National Program for STD/AIDS indicators. Two groups of proposed indicators were analyzed in 2002 and 2005 respectively, as part of the monitoring of the progress of the UNGASS Declaration of Commitment. The availability of information and limitations in calculating the proposed indicators in Brazil were analyzed and the appropriateness of the indicators for monitoring the epidemic in Brazil was discussed. Of the 13 quantitative indicators originally proposed by UNGASS, five were not included in the National Program. One was not included due to its qualitative nature. Two of the indicators were considered to be of little use and two were not included due to the lack of available data needed for their calculation. As the epidemic in Brazil is characterized as being concentrated, within the second group of proposed UNGASS indicators those that refer to the accompaniment of epidemic among high-risk population groups were prioritized. The study highlights that the National Program concentrates its efforts in the development, adaptation, and sharing of sampling methodologies for hard to reach populations. Such activities are geared towards estimating the size of vulnerable population groups, as well as obtaining more information regarding their knowledge, attitudes, and practices. The study concludes that by creating the possibility of international comparisons between advances achieved, the proposal of supranational indicators stimulates countries to discuss and make their construction viable. In a complementary way, the national monitoring systems should focus on program improvement by covering areas that permit the evaluation of specific control and intervention actions.
